浅谈预制桩与石笼在高路堑边坡防护中的联合应用浅谈预制桩与石笼在高路堑边坡防护中的联合应用 摘要: 钢砼防护、圬工防护以及植被护坡作为传统的边坡防护方法,在我国的各类公路上应用的非常广泛,但是受限于其造价不菲,因而很难在低等级的公路上得到更多的应用,尤其是在非洲某些国家的公路基础建设中。因而,选择一种简便快捷,造价低廉,施工工艺简单的边坡防护成为一种必定。本文先介绍路堑防护的主要类型,然后浅谈非洲东北部某低等级公路项目预制水泥桩和铁丝石笼在高路堑边坡防护中的联合应用。 关键词: 水泥预制桩;铁丝石笼;路堑边坡;非洲东北;低等级公路 Abstracts: There is wide application of reinforcement concrete protection, masonry protection, plant protection as traditional slope protection measures for different roads in our country. But due to the limitation of expensive cost, it is difficult to widely apply them to low class roads, particularly the road construction in some African countries. Therefore, it becomes necessary to find an easy, simple and cheap slope protection technique. This thesis introduces some main types of cutting protection and then discuss generally the joint application of precast pile and steel wire gabion for high cutting slope protection in some low class road project in Northeast Africa.
